Steps:

1. Remove the data cable from the amplifier by pulling during pressing the plug on both sides
2. Remove the 4 crews on the sides and the 3 screws on the back to remove the cover

3. The laser is located under the laser protection shield
4. You can move it closer by turning the white gear to get better access to clean it

5. Take a microfiber cloth or any clean cloth which is lint-free
6. Wrap it around a flat screwdriver and soak it with high-percentage cleaning alcohol. I used 80% alcohol and it worked fine
7. Clean gently and carefully the lense
8. Turn the laser back to its standard position with the gearwheel
